Abstract
The effect exerted by a composition of brazing filler metals on structure, chemical heterogeneity and mechanical strength of brazed joints in dispersion-strengthened alloy Glidcop Al-25 was investigated. It is shown that along with the composition of a brazing filler metal, the significant role is also played by a pre-brazing heat treatment. Strength of the brazed joints was found to be 380-400 MPa in the case of using a heat-treated base metal and the optimised composition of a brazing filler metal.
Keywords: dispersion-strengthened copper alloy, vacuum brazing, brazing filler metal, brazed joint, microstructure, strength
